This works for most Android smartphones, but if you don’t find this setting on your smartphone, below is the list of smartphones with the steps to change the font size.

Not all smartphones have a font size option; if your phone doesn’t have one but runs on Android, this app will do the trick. This app changes the font size throughout the interface and works on all Android smartphones.

This app works on all Android smartphones, so irrespective of the Android version your phone runs on, it will do the job. It works better on the previous version of Android OS than the newer version.

Method 3 – Change the Display Size

Changing the display size is another option to increase the size of the user interface elements. It also looks a bit better than just changing the font size on the smartphone. Follow the steps to change the display size according to your smartphone brand.

Stock Android OS or Pixel Smartphones

1. Go to Settings > Display and select Display size and text.

Method 4 – Change the Font

If the default font on your smartphone is small and hard to read, then maybe change the system font to something more readable. This setting is also different in different smartphones; check out your brand.

Stock Android and Pixel Smartphones

Google Pixel smartphones or smartphones with stock Android interface won’t let you change the system font. But you can enhance the font slightly, like bold, or increase the contrast to increase the readability.

1. Open Settings and go to Display.

2. Open the Display size and text option.

3. Enable the Bold toggle and/or the High-contrast text toggle.

These options enhance the system font to make it more readable than the default font. Other than that, there is no way to change the font style on Pixel smartphones.

Samsung Galaxy Smartphones

Samsung smartphones let you change the font style easily from the settings. You can also download a theme from the theme store to change the system font.

1. Open Settings and go to Display.

2. Select Font size and style and then open Font style.

3. Choose one of the available fonts.

More fonts can be downloaded from the Galaxy store to change the system font. Most of the fonts in the Galaxy store are paid, but at least you are getting an option.

Method 5 – Change Font Size in Browser

It is effortless to zoom into any webpage when browsing a website for your convenience, but it won’t be enjoyable when you have to do it every time. Here is a trick to set the font size to your preferred amount, and the website will automatically load with that font size.

1. Open the Google Chrome browser and go to Settings.

2. Select the Accessibility option from the settings menu.

3. Use the slider to set the text size; the preview window will show you how the font will look on websites.

There are more settings to customize the experience, and you can even force some websites to zoom the font even if that website does not allow it. This feature is available on all the mobile browsers under the accessibility settings.

Method 6 – Change Font Size in Messages

The default message app in most Android smartphones lets you change the message text size. You only need to open the message thread in your smartphone’s default message app. Now, use the pinch gesture to change the font size; pinch out to increase and decrease the font size. This feature is unavailable on iPhone, so you must use the screen zoom accessibility feature to zoom in to read the messages.

Method 7 – Change Text Size in WhatsApp

WhatsApp has a font size setting to adjust the text size in chats. If the above tricks don’t increase the font size in WhatsApp chats, follow this trick to increase the font size.

1. Open WhatsApp on your smartphone and tap the profile picture to open the settings menu.

2. Scroll to find the Chats option.

3. Here, tap the Font size option and select the Large option from the pop-up.

This will increase the size of the chats in WhatsApp. Remember that this will only change the font size in chats, not WhatsApp’s user interface.

Method 8 – Change Text Size in Telegram

Telegram, like WhatsApp, also has a feature to change the font size in the settings to enhance readability. Follow the steps to change the font size in Telegram chats.

1. Open the Telegram app and go to Settings.

2. Select Chat settings.

3. Use the slider to change the font size in chats.

Like WhatsApp, the font size changes only for the chats and not for the user interface. So, use other zoom tricks to zoom in on the interface elements and texts.

Method 9 – On Rooted Smartphones

If your smartphone does not have font settings, you can try rooting your phone. This will give you many customization options, including changing the font style and size. We often don’t recommend rooting your smartphone because of security and warranty issues. But if you need to change the font so severely, rooting your smartphone is the only way to get it.

Method 10 – Use Magnification (Android/iOS)
